Abstract
1,260,362. Aromatic copolyamides. FARBENFABRIKEN BAYER A.G. 13 March, 1969 [13 April, 1968], No. 13288/69. Heading C3R. Linear aromatic copolyamides comprising units are made by polycondensing an ester of formula with equimolar amounts of a diamine and an iso- and/or tere-phthalate ester at 150‹ to 350‹ C. until the relative viscosity is above 1À18. R 1 is alkyl or aryl, R 2 and R 3 are optional alkyl, aryl or Ha substituents and R 5 is phenylene, alkyl-, aryl- or halo-substituted phenylene, diphenylene or diphenylene ether or 2,2-propane. A basic catalyst may be used and the polycondensation effected in the melt or solution or both, e.g. to over 80%, preferably 95%, in the melt and completed in solution. Solutions of the polymers, e.g. in N-methylpyrrolidone, dimethyl formamide or sulphoxide, or hexamethylphosphoric acid triamide may be used to cast films. Preparation of the copolymers via the acid chlorides of the monomers is disclaimed.
